Bankston was a conductor on the Alabama Warrior Railway, a job he had held for seven months when Tuesday's accident happened, said Ed McKechnie, an executive vice president for Watco, the railway's parent company.
Bankston, 27, was a contestant on "Survivor: Blood vs. Water" last year, along with his fiance, Colton Cumbie, according the CBS show's website.
"Our prayers continue to be with Caleb and his family," railway Senior Vice President Dan Smith said in a written statement.
The railway began a "safety stand down" Wednesday morning, sending its workers to sessions "to ensure all team members understood that nothing is more important than their safety," the company said.
Federal Railroad Administration investigators were on the tracks Wednesday looking at what caused the accident, according to a railway statement.
"Once completed, our investigation will identify the root cause of the accident, and we will take all appropriate enforcement actions," Federal Railroad Administration spokesman Warren Flatau said.
